Question

The decomposition of n2o5 can be described by the equation 2n2o5(soln)⟶4no2(soln)+o2(g) consider the data in the table for the reaction at 45 ∘c in carbon tetrachloride solution.

Answer 1

The reaction rate between 0 -195 seconds for the decomposition of N2O5 is 0.0006 M/s.

What is the rate of a reaction?

The rate of reaction can be estimated in terms of the consumption of the reactants in the reaction.

From the given information, the equation N2O5 has been the reactant that has been used in 2 moles.

The rate of the reaction is expressed as:

$\mathbf{Reaction \ rate = -\dfrac{1}{2} \times \dfrac{dN_2O_5}{dt}}$

The reaction rate for a time interval between (0 - 195) sec is expressed as follows:

$\mathbf{Reaction rate = -\dfrac{1}{2} \times \dfrac{1.86556-2.10195}{195s - 0s}}$

$\mathbf{Reaction \ rate = -\dfrac{1}{2} \times \dfrac{-0.23639}{195s}}$

= 0.0006 M/s.
